Patent DE-3205362-A1 (DE)
Title: Spatial displacement measuring system
Inventor: TRAPET EUGEN
IPC: G01B11/03
Filed: 1982-02-15
Abstract: Modern production measurement technology urgently requires methods which enable spatial detection with uncertainties below 1  mu m, in particular for the acceptance of multi-axis measuring and processing machines, and of object positions or object motions. According to the invention this object is achieved when three laser interferometers are arranged such that the beams which traverse the measuring distance are rotated in each case about a point on these beams in such a way that they represent the shortest connecting lines between the points of rotation serving as reference points and the point of the test specimen to be measured, which is generally embodied by the corner of a triple reflector. By contrast with virtually all machine measuring systems existing today, this mode of procedure does not infringe the comparator principle (no Abbe errors). According to the invention, the problem of precisely determining the reference point coordinates required for the conversion, e.g. in Cartesian coordinates, and of determining an initial value for the movable object point to be measured is achieved by the use of (at least) four interferometer systems, without this requiring further measuring means.

Title: Apparatus for applying preferably foamed liquors onto sheet-like materials, especially material webs
Inventor: MITTER MATHIAS
IPC: D06B19/00
Filed: 1982-07-16
Abstract: When media, such as, for example, foamed liquors, are being applied onto material webs of relatively large width, a uniform distribution of the medium to be applied is necessary. The applicator apparatus according to the invention is characterised by nozzles which are designed as distributor heads for the application of the medium. The nozzles are connected conductively to the foam feed pipes located inside or outside the applicator apparatus. The applicator apparatus is equipped with a foam-receiving space, into which the nozzles open. A displacement body for the medium to be applied is arranged centrally in the applicator apparatus, with the result that throughflow channels for the medium to be applied are formed between the outer wall of the displacement body and the inner wall surface of the applicator apparatus. The nozzles can be designed as round-head nozzles or as flat-jet nozzles. If flat-jet nozzles are used, it is expedient, for the uniform distribution of the medium to be applied, that the outlet orifices lie alternately in opposite directions. <IMAGE>

Patent DE-3248356-A1 (DE)
Title: Heat pump system
Inventor: IMANISHI MASAMI
IPC: F25B41/04
Filed: 1982-12-28
Abstract: In the heat pump system according to the invention, the opening amount of an expansion valve (40) is adjusted to an optimum value depending upon the inlet temperature of water, which is subjected to a heat exchange on a use-side heat exchanger (9), and the inlet temperature of air which is subjected to a heat exchange on a non-use-side heat exchanger (3). On the basis of the detected temperature values, a controller (30) determines the optimum amount of valve opening in order thus to provide a maximum system capacity and a maximum system efficiency. The controller (30) can be equipped with a microprocessor and a read-only memory. In the read-only memory, data values are stored, which store the optimum opening adjustments of the expansion valve corresponding to the different values of the detected inlet temperature of the water on the use-side heat exchanger (9) and the inlet temperature of the air on the non-use-side heat exchanger (3). <IMAGE>

Title: Semiconductor laser having a colliminating lens and method for producing the housing upper part
Inventor: SCHMID WOLFGANG
IPC: H01S5/022
Filed: 1983-01-13
Abstract: The invention relates to a semiconductor laser having a colliminating lens and a method for producing it. Use is made as colliminating lens of a spherical microlens 7 which is inserted concentrically into a housing cap 2. The housing cap 2 is produced as a rotary part and mounted on an accurately fitting positioning ring 1. In order to adjust the optical arrangement, the positioning ring 1 can be displaced onto the housing floor in the horizontal direction, and the housing cap 2 can be displaced vertically with respect to the positioning ring 1. As soon as the desired position of the lens 7 with respect to the light-emitting semiconductor element 5 is reached, the housing floor 3 and positioning ring 1 are welded to one another, as are the positioning ring 1 and housing cap 2. The use of a short-focal-length microlens leads to an exceptionally compact design for the entire arrangement. <IMAGE>

Patent DE-3310198-A1 (DE)
Title: Collapsible surf board roller assembly
Inventor: SCHLINK GERD DIPL ING
IPC: B63B35/79
Filed: 1983-03-21
Abstract: The problem of constructing a surf board roller assembly which is easy to handle is achieved in that it consists essentially of an upper part and two identical V-shaped side parts which each bear a wheel. The surf board roller assembly can be collapsed without fitting operations in such a way that in the transport state the side parts form a large, plane surface so that it can be conveniently loaded. After being raised, the side parts move automatically (under spring force) into the operating state. For this purpose, a special design and position of the side parts is required, the specific arrangement in each case of one axis of rotation and folding axis per side part, the specific arrangement in each case of one strut and the use of rubber bands or springs being also required. There is provision for the surf board roller assembly to be produced predominantly or entirely in plastic. The enclosed drawings show     a side view in the operating state and   a bottom view in the transport state.   <IMAGE>

Title: Process and device for welding the edges of plastics webs
IPC: B29C65/18
Filed: 1983-07-13
Abstract: The present process of so-called thermal welding serves for welding the edges of webs of plastics, especially PVC and copolymers, the edges to be welded being heated until they soften and simultaneously pressed together. In order to use higher temperatures in the welding, according to the present process the edges to be welded are covered on both free outer surfaces with one separating layer in each case before being pressed together and then the edges are pressed together over the entire length between heated rails for an adjustable welding time and with an adjustable welding pressure. Subsequently the separating layers adhering lightly at the edge regions can be stripped off the webs welded together at their edges. A device of frame-like design is provided for carrying out this process, having a support table for the two-part welding tool and a roll stack for drawing in the separating layers. <IMAGE>

Title: Switching arrangement for the stitch control of a sewing machine
Inventor: TAKENOYA HIDEAKI
IPC: D05B19/02
Filed: 1983-09-16
Abstract: To reduce the necessary power of the control motors for the needle position and the fabric feed, these are controlled by a switching arrangement, in which the stitch control data read from the pattern memory are each stored in latch circuits. When stitch control data are extracted from the pattern memory, computing circuits form the respective difference between these data and the particular previously read data stored in the latch circuits. By adding these differences, a total value needed for controlling the needle position and the fabric feed is then calculated. When the total value is higher than a predetermined maximum value, the address counter of the pattern memory is counted down.
